Wonderful idea Arnie; especially if you want the "2nd" tune. 73 George AI4VZ -------------------------------------------------- From: "Arie Kleingeld PA3A" <pa3a at xs4all.nl> It would be a nice feature that when I press the tune button on the KAT500, it would key the K3 at the same time and put theKPA500 in standby (if you have one).
